TinyQ

Very easy and fast channel strip style EQ that doesn't use more than 0.2-0.3% CPU (i7-8559u) when all bands and both filters are active and at most 0.4-0.5% when the analyzer is also active. From what I can see it has a type of symmetrical proportional Q which is very musical and easy to set, especially when you can either turn the knobs or just drag the bands around on the graph directly. I would like to have the option to set it to asymmetrical for a even faster workflow but considering that it's free, it already does a lot! Another very important, and impressive detail for a free EQ, is that there is no cramping at all near Nyquist. This is a real issue I have with many free EQ's, and even some stock and paid-for ones. This one however, sounds airy and open in the high frequencies. The low- and high-pass filters are also great with the option to set steepness of the slope from 6dB/oct all the way to 48dB/oct. Not something I would use very often in a minimum phase EQ but it's nice to have the option to. You can also set the gain range for the frequency graph, enable the analyzer for either the input or output and sort the bands if you have messed around with them. All in all, a very feature rich little EQ that doesn't take up much space or CPU, and it's free! Crazy.

If this would evolve later on into a paid-for EQ, where you have a couple of more bands, asymmetrical setting and a linear phase mode, I would happily pay for it.
